Holding Owners of Compromised Computers Responsible

I've heard several people refer to legal activity in Texas, where victims of intrusions were being sued when the original victim's systems attacked third parties. This happened in 2001, when systems at Exodus were allegedly compromised and used to attack Web-hosting company C.I. Host. Marc Zwillinger mentioned this is this webcast, saying the suit was moved to Federal court and then settled out of court. His slides included this scan of the indictment. From this article:


JUST BEFORE 8 A.M. ON FEB. 1, 2001, C.I. Host, a Web-hosting company with 90,000 customers, was hit with a crippling denial-of-service attack. By the end of the day, after outage complaints from what CEO Christopher Faulkner described as "countless" customers, the Fort Worth, Texas-based company got its lawyers involved. . . In an injunction filed in a Texas district court and later moved to a U.S. district court, C.I. Host alleged that the defendants committed or allowed a third party to commit a denial-of-service attack on C.I. Host's systems. The defendants insisted that they were victims of a hacker themselves, not the perpetrators of a crime. The case never made it to trial, but C.I. Host's lawyers did convince a Texas judge to issue a temporary restraining order shutting down three of the Web servers involved in the attack until the companies could prove the vulnerabilities had been fixed.


The other popular case is well-documented in the 2001 CSI/FBI Study:


The U.S. Navy's Criminal Investigative Service (NCIS) is in the throes of an investigation into how and why an as yet unidentified hacker stole the source code to OS/Comet from a computer at the U.S. Navy's naval research lab in Washington, D.C. in an attack conducted on Christmas Eve, 2000. OS/Comet was developed by Exigent International (Melbourne,FL), a U.S. government contractor. The software has been deployed by the U.S. Air Force on the NAVSTAR Global Positioning System (GPS) from its Colorado Springs Monitor Station, which is part of the U.S. Space Command. A copy of the OS/Comet source code was found during a police swoop in Sweden on a computer company whose identity has not been revealed. The intrusion appears to have emanated from a computer at the University of Kaiserslauten in Germany, which was used to download the software's source code via the Web and the service provider Freebox.com, which is owned by the Swedish firm Carbonide. The hacker known only as "Leeif" was able to hide his or her true identity by breaking into the account of a legitimate Freebox.com user and then using that person's account to distribute the source code to others. Exigent has filed suit against both Carbonide and the University of Kaiserlautern in Germany. The NCIS's inquiry is being headedby the NCIS headquarters for European affairs in Naples and by its London bureau, which deals specifically with Scandinavia.

Zeek in Action Videos

Image
This is a quick note to point blog readers to my Zeek in Action YouTube video series for the Zeek network security monitoring project .  Each video addresses a topic that I think might be of interest to people trying to understand their network using Zeek and adjacent tools and approaches, like Suricata, Wireshark, and so on.  I am especially pleased with Video 6 on monitoring wireless networks . It took me several weeks to research material for this video. I had to buy new hardware and experiment with a Linux distro that I had not used before -- Parrot .  Please like and subscribe, and let me know if there is a topic you think might make a good video.

MITRE ATT&CK Tactics Are Not Tactics

Just what are "tactics"? Introduction MITRE ATT&CK  is a great resource, but something about it has bothered me since I first heard about it several years ago. It's a minor point, but I wanted to document it in case it confuses anyone else. The MITRE ATT&CK Design and Philosophy document from March 2020 says the following: At a high-level, ATT&CK is a behavioral model that consists of the following core components: • Tactics, denoting short-term, tactical adversary goals during an attack; • Techniques, describing the means by which adversaries achieve tactical goals; • Sub-techniques, describing more specific means by which adversaries achieve tactical goals at a lower level than techniques; and • Documented adversary usage of techniques, their procedures, and other metadata. My concern is with MITRE's definition of "tactics" as "short-term, tactical adversary goals during an attack," which is oddly recursive. The key word in the tacti
